Application led December 4, 1914. Serial No. 875,537.

To all lwhom t may concern Be it known that I, WALTER M. SCHWARTZ, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented 4certain Improvements in Drying-Machines, of which the following is. a specification.

My invention relates to certain improvements in drying machines of the type in which an endless chain travels through a drying compartment and the material to be .drled is carried by the chain.

Une object ofthe invention is to construct the conveying means so that-a single chain can be employed to carry the .material to be l ports can bemounted on each side of the chain.

In the accompanying drawings: Figure 1 is a front view of my improved machine; Fig. 2 is a sectional plan view on the line a-a, Fig. 1; Fig. 3 is aside view; Fig. 4 is a longitudinal sectional view of a portion yof the apparatus atthe feed end thereof;

Fig. 5 is an enlarged sectional view through the track and the conveyer, showing the conveyer suspended from a rail; and Fig. 6

is a perspective view lof a portion of the chain and the horizontal supports connected thereto. v

Referring to the drawings, 1 is the casing of the conveyer made in any suitable manner. In the present instance, it consists of a frame composed of a series of metal shapes 2 and'mounted on the frame is a series of panels 3, which inclose the chamber. It will be understood that the length of this casing will depend upon the material to be dried as it may be of any length desired. In the upper portion of the drying chamber isa fan 1, mounted on a suitable shaft 5, which has its bearings in a frame 6 and is driven from -a horizontal shaft 7 through bevel gearing. While in the drawings only one fan is shown, it will be understood that any number of fans may be used according to the length of the casing. At each side of A the chamber formed by the casing are coils 3 of heating pipes so that, when' the fan is 1n motlon, there is a constant circulation of air through the casing, the steam pipes heating the air to the proper temperature.

9 is a series of longitudinal rails, spaced a given distance apart, and located at a proper height to allow material to be suspended from the conveyer which travels on the rails.- These rails are made as shown in Fig. 5, and have inturned flanges 10 on which travel the wheels 1-1 from which is 'suspended the chain 12. This chain 12 is composedof a series of links 13 and the links 13a have the brackets 14 on which the axles of the wheels 11 are mounted, and also have depending portions 15. In the present'instance, projecting from each side of this depending portion 15 are spindles 16 on which are mounted spools 17 These spools are preferably held from turning by any suitable means, so-that the material thereon will not accidentally slide from the spools.

Each of the spools is preferably provided with a head so as to retain the material in position but, in some instances, where the spools are of a suitable length, or the spindles are used without the spools, then the heads may bedispensed with.

It will be understood that the present machine is designed for drying comparatively .narrow material, such as narrow woven fabric. The machine, however, may be designed for diferent widths of material without departing from the essential features of the invention. Furthermore, the

spindles may be located at oneside only of the chain when necessary and while I have illustrated mechanism for feeding a continuous band of fabric to the machine, single pieces of material may be mounted on the horizontal spindles, or spools, traversed through the machine without departing from the spirit of the invention. In this apparatus, a single endless conveyer chain is used and it enters the casing through the opening 18, Fig. 2, and is supported by the first rail and passes around a sprocket Wheel 19 at the rear end of the machine and returns and passes around a sprocket wheel 20. There is `a series of these sprocket wheels 19 and 20, at the rear and at the front of the machine, as Shown in the plan view, Fig. 2, and after the chain traverses the last rail 9 it passes out through the opening 21 and then around a sprocket wheel 22 35 is fed to the apparatus. 31-is a clutch controlled by the lever 32 for throwing the feed and a sprocket wheel 23, where it again'enters the opening 18.

A sprocket wheel 24 is arranged so as to take up any slack in the chain in order that the chain will be taut throughout the entire apparatus. A rail 25 supports the chain as .it travels-from the sprocket wheel 22 to the sprocket wheel 24 and, as above remarked, the material may be placed on the spindles,

or spools, by hand and removed therefrom by hand, or it may be placed thereouby machinery and automatically Nremoved by mechanism which I will now proceed to describe. Mounted in front of the drier is a frame 26 on which are mounted .the feed, rolls 27,28 and 29, which feed the fabric forward in the present instance and into the casing. The roll 29 is solocated that it eX- tends into the chamber formed by the casing so that the fabric .fr is discharged from the inner end of the roll 29 and passes down` between two spindles, as clearly shown in Fig; 4,' and the mechanism for driving the chain is so mounted that it willlmove to allowa loop of the fabric to be formed between the two spindles. In order to prevent the ljoop being formed from disturbing the loop `previously formed, a detent in the form of a pivoted arm 30 is located so as t0 engage the fabric on the spindle between the two loops and it will hold the fabric throughout the formation of the loop being formed. This detent is released as the chain moves forward and engages the fabric on the next spindle and so on as the material mechanism out of gear when it is necessary. At the discharge end of the machine is a roller -33 over which the fabric passes after it has been dried and it passes between two rollers 34 and 35 and into a hopper' 36 and through a discharge spout '37, which is moved vto allow the material to fall on a platform, or floor, without tangling. In the present instance, there is sufficient width to the feed rolls to take two strands of material and to feed one strand to the spindles on one side of the chanand the other strand to the .spindles ony the opposite side. The

discharge rollers 33, 34 and 35 are of sucient widthl to take both strands, but there are two hoppers at the discharge end and two spouts. One strand is fed to one hopper and spout 'and the other strand is fed to the other hopper and spout and these sp'outs are spaced a suilicient distance apart in order that onepile of material will not become entangled with the other pile. \Any suitable the chain passing around the' several sprocket Wheels; a series: of spindles arranged horizontally and carried by the chain below the rails; means for feeding material to the spindles after they have entered the chamber; and means for removing the material from the spindles before they leave the chamber.

In testimony whereof, I have signed myy name to this specification, in the presence of two subscrlbing wltnesses.
